the product of two integers is between +160 and +200. One integer is between -20 and -40. What is the greatest and least possible value fir the other integer?
The farthest apart numbers if you just look at their absolute value:
-20 * a = 200
a = -10
The closest together numbers if you just look at their absolute value.
-40 * b = 160
b = -4
The smallest is -10. The biggest is -4.
